I've built a lot of delta-wing aircraft versions on my pc and all of them have a proper working canards - they do roll/pitch properly using 2 small rotators per canard, yes rotators are placed into each other. While this looks somewhat easy to do, it is just so annoying to fix those damn canards to work. Sometimes only one canard works, sometimes left one has roll/pitch while right can only pitch or roll, sometimes canards just don't move though they ARE connected to rotators, sometimes they ARE connected and of course one or both drop on the ground before throttling up. Doing that Shift + QWEASD thing to fix these problems is time-waster and of course going directly to XML do not help a lot ...

So, what are your recipes for problems like this one?
